The Argo Simulation: II. The Early Build-up of the Hubble Sequence

Understand

The Hubble sequence is a common classification scheme for the structure of galaxies.

• Despite the tremendous usefulness of this diagnostic, we still do not fully understand when, where, and how this morphological ordering was put in place.
• Here, we investigate the morphological evolution of a sample of 22 high redshift ($z\geq3$) galaxies extracted from the Argo simulation.
• Argo is a cosmological zoom-in simulation of a group-sized halo and its environment.
